opening the database administration dialog. After selection, a dialog will open with three buttons:

Backup: saving your current local recording database to the AIRS data partition (usually under /sdcard/Android/data/com.airs/files

Restore: restores any previous backup file, replacing the current database (cannot be undone!)

Index: creates an index over the timestamp entry in the local recording database. This speeds up any visualisations tremendously but will increase the size of the database by about 60%. The index needs only be created once and cannot be removed after created!
